Oxidative Stress News and Research

RSS

Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Scientists find a universal gut microbiome pattern linked to colorectal cancer

Researchers analyzed 6,779 stool microbiome profiles and 906 tissue samples to identify a colorectal cancer microbial signature that remained consistent across age groups, populations, and sequencing methods. The signature aligned with tumor-resident microbes, showed weaker detection for adenomas, and was inversely associated with dietary fiber intake.

Study identifies fPRDM16 as target for age-related pulmonary fibrosis

A study published recently in Current Molecular Pharmacology has uncovered a key mechanism linking aging to persistent pulmonary fibrosis, identifying the transcriptional regulator fPRDM16 as a potential therapeutic target.

Blueberries may boost children's memory and mood

Research suggests blueberry compounds could enhance mood and cognitive function in children, yet stronger evidence is required for clinical recommendations.

Gene linked to lower BMI points researchers toward a new obesity target

A review in Cardiology in Review highlights GPR75, a receptor for 20-HETE, as a promising therapeutic target for obesity and metabolic syndrome. Evidence from genetic studies, cell experiments, and mouse models suggests that blocking this pathway could influence weight gain, insulin resistance, hypertension, inflammation, and vascular dysfunction.

Scientists identify genes linking air pollution to severe asthma

For many people with asthma, air-quality advisories are harbingers of worsening symptoms. But for reasons science has struggled to explain, the extent to which pollution exacerbates asthma varies widely from person to person.

Melatonin improves skin flap survival by reducing ferroptosis

Random-pattern skin flaps are widely used to repair defects caused by trauma, burns, tumor removal, and other injuries because they can be designed without depending on a single named blood vessel.

Key Alzheimer's protein actively protects neurons from nuclear damage

Researchers at Niigata University's Brain Research Institute have uncovered a new function of amyloid precursor protein (APP), a molecule long studied as the precursor to amyloid-β (Aβ) in Alzheimer's disease (AD).

New study uncovers how prostate cancer cells evade treatment

Cancer cells are remarkably good at adapting to stress. When treatments damage them, they often find new ways to survive, fueling drug resistance and disease progression.

Lysosomal protein stabilizes mitochondria to prevent severe heart failure

A new study published in Engineering has uncovered a regulatory mechanism linking lysosomal function to mitochondrial stability in pathological cardiac hypertrophy, identifying transient receptor potential mucolipin 1 (TRPML1) as a key protective factor against the progression to heart failure.

Gut bacteria may help explain why fatigue appears before illness

A small study of healthy Japanese adults found that fatigue was associated with distinct gut microbiome, microbial gene, and fecal metabolite patterns. The findings suggest fatigue may track with altered microbial energy metabolism and oxidative stress-related functional potential, but larger longitudinal studies are needed to test causality and clinical value.

Western diet weakens the gut’s nervous system through iron-dependent damage

A JCI study found that exposure to a Western diet in mice and to palmitic acid in murine and ex vivo human enteric nervous system models triggered ferroptosis, characterized by iron loading, lipid peroxidation, mitochondrial stress, and enteric neuronal loss. Boosting Nrf2 signaling protected enteric neurons and prevented Western diet-induced delayed colonic transit in mice, pointing to a potential pathway linking dietary fat exposure to gut motility dysfunction.

Short-term fasting may reduce inflammation linked to gum disease

People who follow a short-term low-calorie diet may have reduced markers of inflammation associated with gum disease.

New DNA tetrahedron nanostructures improve targeted cancer therapy delivery

Conventional cancer treatments, such as chemotherapy, often lack specificity and can damage both cancerous and healthy cells, leading to severe side effects.

Study identifies new therapeutic candidate for KRAS-driven pancreatic cancer

A new research paper was published in Volume 17 of Oncotarget on June 3, 2026, titled "The anticancer effects of PCAIs in pancreatic cancer cells involve MAPK and PI3K/AKT pathways hyperactivation."

What older adults eat may shape dementia risk

Higher ultraprocessed food intake was associated with increased risks of dementia, cognitive impairment with no dementia, and the combined outcome among older US adults in the Health and Retirement Study. Minimally processed food intake showed the opposite pattern, although the observational findings require cautious interpretation because diet was self-reported and cognitive outcomes were not clinically diagnosed.
